Yin Seal

Several days have passed since Naruto left us.

In a laboratory.

"Waaaaah~ I'm already a salted fish!"

The pink-haired girl slumped in the chair, half of her upper body pressed against the table, emitting listless groans.

Around her, on the table, at her feet, and on the floor, were piles of all sorts of scrolls and papers, most of which were sealed papers covered with unknown spells.

"The Sealing Jutsu technique of the Yin Seal is actually so complex!"

Sakura Haruno scratched her hair and said weakly.

The reason Cherry Blossom Impact is learning the Yin Seal now is not because she has completed the second stage of her Ninjutsu and is starting to learn the next one, but because it was Tsunade's suggestion.

As Cherry Blossom Impact's development progressed, the amount of Chakra consumed in each experiment gradually increased. Often, she would spend a whole morning doing experiments, only to run out of Chakra in just one or two hours.

"You don't usually use up all your Chakra when doing missions, so you often have a lot of Chakra and stamina left. In that case, why not learn the Yin Seal first and accumulate the extra Chakra you have every day? You can use it when you're doing experiments."

That's how Tsunade is.

In short, the key to success is having the right tools.

That makes a lot of sense.

But how do we manage tens of thousands of Sealing Jutsu?!

When she opened the scroll of profound secrets Yin Seal, thousands of sheets of paper filled with spell formulas suddenly appeared, almost drowning her in the pile of papers—Sakura almost thought she had opened the blueprint library of the Dalian aircraft carrier.

The number is staggering.

The Yin Seal is Ninjutsu passed down by Mito Uzumaki, the wife of the First Hokage. Before that, this Ninjutsu had been developed and researched for a long time by the Uzumaki Clan, who were proficient in Sealing Jutsu. That's why it has become so extensive, and almost no one can fully understand it.

Fortunately, Tsunade told her that she only needed to draw the patterns on her body one by one, without needing to understand the meaning of the techniques.

However, even so, it's not a simple matter. When the number of runes reaches a certain level, some things that weren't problems before become problems.

For example, how can so many runes be written on a body with such a limited surface area?

The answer is a matching Rune Reduction Printing Jutsu, which Tsunade thoughtfully included with the Yin Seal blueprints: it can shrink a palm-sized rune to the size of a grain of rice while maintaining clarity and stable function.

In addition to this Ninjutsu, there are two thick user manuals and detailed explanations of the technique, covering everything from how to use it to potential problems.

The girl was certain that without this user manual, even if all the techniques used in the Yin Seal were revealed, no one would be able to successfully use the Yin Seal without the assistance of a room full of experts proficient in Sealing Jutsu.

This thick manual and tens of thousands of Sealing Jutsu techniques embody the wisdom of the Uzumaki Clan. In the Hokage world, which reveres power, this Ninjutsu is truly a breath of fresh air.

Its usage is incredibly simple; just write the incantation on your body according to the manual, and you can use it. No understanding or practice is required...

The Yin Seal is the only Ninjutsu that Tsunade felt her disciples could skip over and not fully understand. In fact, even she herself didn't fully comprehend the meaning of those tens of thousands of runes. It's likely that there weren't many people in the Uzumaki Clan who could fully understand this technique back then.

However, Sakura detests this kind of approach of knowing the "how" but not the "why." Her personality dictates that she must thoroughly study the Ninjutsu she frequently uses, then add her own personal style, until she completely transforms it before she stops.

So this girl, unaware of the hardships of the world, resolutely opened the manual and explanations, intending to fully understand this Ninjutsu that even Tsunade hadn't completely mastered.

Then, an hour later, she became the listless, unmotivated person she was at the beginning of this chapter.

Wow, I've lost my penis, what's the point of talking about Ninjutsu? Forget it, let me just be a salted fish. (Oops, wrong words, scratch that)

Tens of thousands of runes, the culmination of generations of hard work, are not something a naive girl like her could understand all at once.

With the annotations, she managed to understand the simplest part: the entire Sealing Jutsu technique, in fact, largely serves to maintain the stability of the Sealing Jutsu itself, forming a solid framework.

Within the framework are the unique contents of the Yin Seal, which can be simply divided into two parts: one is the energy storage part, which can convert the Chakra extracted from the human body into other forms of energy and store it in crystal form; the other is the energy release part, which releases the energy stored in crystal form as Chakra.

However, when it comes to the specifics of how these techniques achieve their functions, Sakura is completely baffled.

It's like seeing a drawing tutorial online. The first step is to draw two eyes, a nose, and a mouth, then a head and a body, and finally fill in the details, and a lifelike portrait is born! The key question is, how exactly do you fill in the details? The second step is still a student's doodle, but the third step becomes a realistic portrait. What happened in between?!

For example, the energy storage section consists of tens of thousands of spell runes. If you look at them individually, there are many runes whose meanings she doesn't recognize, let alone the complex structure they form when combined.

Sakura had learned some basic Sealing Jutsu at the Ninja Academy, and she could store water for ninja tools or Ninjutsu within Sealing Jutsu. These formulas usually consist of a few to a few hundred runes, with a relatively simple structure and using the most basic runes.

However, the Yin Seal is far from simple. It involves the complex human body, with fifty trillion cells, so it cannot be treated as simply and crudely as steel ninja tools. Therefore, the number of runes used here suddenly jumps from a few hundred to more than ten thousand.

However, if Sakura can truly understand the contents and innovate upon them, then releasing a Sakura Haruno version of the Yin Seal wouldn't be difficult. This Yin Seal is actually quite workable; as soon as Sakura received the scroll, she began to unleash her imagination, and many ideas immediately popped into her head.

For example, if she created many clones of herself, and then used the Yin Seal to concentrate their Chakra —mainly their physical strength—and transfer it to herself, wouldn't she gain an inexhaustible source of Chakra?

"Hmm, the 20,000 Sakura Haruno Sisters Project is officially launched," the girl thought happily.

This project doesn't actually require many changes to the Yin Seal; it still involves storing the Chakra generated by the clones within the Yin Seal —of course, Sakura will restrict the clones from developing self-awareness, so the spiritual power contained within this Chakra is approximately zero. However, it doesn't matter, as Sakura's own spiritual power is vast enough that it won't cause an imbalance in the Yin and Yang of her Chakra.

Modifications to the Yin Seal are minimal; simply changing the energy storage crystal generation point from the clone's forehead to the original's forehead suffices. This way, she doesn't need to thoroughly research the entire Yin Seal; understanding a specific detail and knowing how to modify it will greatly reduce the difficulty of research and development.

Even without making any changes, it's fine.

She could forcibly remove the Yin Seal from the clone's forehead and give it to the original for use. As long as the clone didn't develop personal consciousness, Sakura wouldn't find this behavior unethical. What a joke! She's in the Hokage world now, still trying to act like a saintly, innocent figure?

She wouldn't refuse anything that could improve her strength, as long as it didn't harm her principles.

(I almost forgot to update because I was watching the IG matches. Both IG and NB won their upper bracket matches today, that's amazing. Liquid and Evil are crying~)
